[Qemu-block] [PATCH 13/18] iotests: maintain several vms in test

[Vladimir Sementsov-Ogievskiy]

The only problem with it is the same qmp socket name (which is
vm._monitor_path) for all vms. And because of this second vm couldn't be
lauched (vm.launch() fails because of socket is already in use).
This patch adds a number of vm into vm._monitor_path
